Name two Oviparous mammals?

(A) Whale, Echidna

(B) Platypus, Echidna

(C) Platypus, Whale

(D) Bat, Echidna

When we talk about oviparous mammals, we're referring to those that lay eggs instead of giving birth to live young. This is quite rare among mammals, as most are viviparous, meaning they give birth to live offspring. Among the options provided, the correct answer is (B) Platypus and Echidna.

Understanding Oviparous Mammals

Oviparous mammals belong to a unique group known as monotremes. This group is characterized by their reproductive method, which involves laying eggs. The two most well-known examples of oviparous mammals are the platypus and the echidna.

The Platypus

The platypus is a fascinating creature native to Australia. It has a duck-bill, webbed feet, and lays eggs. After the female platypus lays her eggs, she incubates them by curling around them. Once the eggs hatch, the mother feeds her young with milk, which she secretes from her skin, as platypuses do not have nipples.

The Echidna

Echidnas, also known as spiny anteaters, are another example of oviparous mammals. They are found in Australia and New Guinea. Like the platypus, echidnas lay eggs. After laying an egg, the female carries it in a pouch on her belly until it hatches. The young echidna, called a puggle, is born very underdeveloped and continues to grow in the pouch, feeding on its mother's milk.

Why Other Options Are Incorrect

• Whale: Whales are viviparous mammals, meaning they give birth to live young.
• Bat: Bats are also viviparous and do not lay eggs.

In summary, the only correct pair of oviparous mammals from the options given is the platypus and the echidna. These unique creatures highlight the diversity of reproductive strategies in the animal kingdom, showcasing how evolution has shaped different life forms to adapt to their environments.
